Description
Same as jacobianAddFreqShift but also adds the correlation block contained in covmat_block and covmat_inv_block to covmat_sx. For number and order of elements added to x, see jacobianAddFreqStretch.

Variables
| OUT | covmat_sx | (CovarianceMatrix) | Covariance matrix of a priori distribution This covariance matrix describes the Gaussian a priori distribution for an OEM retrieval. |
| OUT+IN | jacobian_quantities | (ArrayOfRetrievalQuantity) | The retrieval quantities in the Jacobian matrix. |
| OUT+IN | jacobian_agenda | (Agenda) | Pure numerical Jacobian calculation agenda. |
| IN | f_grid | (Vector) | The frequency grid for monochromatic pencil beam calculations. |
| IN | covmat_block | (Sparse) | Holds matrices used to set blocks in covmat_sx and covmat_se. |
| IN | covmat_inv_block | (Sparse) | Holds matrices used to set the inverse blocks in covmat_sx and covmat_se. |
| GIN | df | (Numeric, Default: 100e3) | Size of perturbation to apply. |
